HDMI Adapter box for " usb uvc webcam video source to HDMI output "

   This box  can let uvc usb webcam become hdmi output

"UVC webcam to hdmi" have many detail technical problem to be solve

1. UVC Webcam video stream

   UVC webcam have  YUV  and MJPG  stream

   YUV means no compression . MJPG menas compression stream.

   YUV  video frame rate will be slower than MJPG video frame rate.

   Each YUV and each MJPG also have difference resolution.


   if you catch 640X 480 resolution, the resolution is bad.


   The best uvc stream that be caught  is  MJPG  1280X720.

    The reason is as below

     reason 1: the frame rate can be 30fps

     reason 2 : the video resolution is HD. video performance is better.

          if you caugh 1920x1080 uvc, the frame rate will be reduce.



2. HDMI output is  1920X1080P

    After getting the uvc stream,  it will be convert to 1920x1080p hdmi output.

        We can not fixed the uvc resoution and uvc format and uvc frame rate.

   so, it must have the ability that can let all of kind of uvc resolution  become  1920x1080p  full HD hdmi output.

LUMENS DC120 實務攝影機變成無線wifi wireless AP,讓 IPAD /IPHONE 觀看預覽的教學應用

Lumens 是台灣前兩大的document camera 廠商

就如同我之前預料的,他一定會看到 愛比科技P2V 那一支usb webcam style的document camera...

沒有想到他竟然也做出 USB 2.0 輸出的document camera.


但是他的價錢卻是 愛比科技 p2v 的10  倍...

站在電子光學設計的角度, LUMENS DC120 他採用的是光學變焦，當然成本不能跟用 手機鏡頭的p2v 做比較...

光學變焦及 光學鏡頭解析度大贏愛比 p2v


但是, 拿豬腳去比雞腿...不能這樣比成本的...


 不管是豬腳還是雞腿...

我拿來跟 FEBON220 WIFI AP 連連看

 果真可以使用！！

IPVEO P2V 大部分的使用方式是直接插入 PC /NB 的USB ，然後再接上投影機，
這樣就可以達到教學用的實物投影機的目的,

如果將畫面打到前面的大銀幕，還是有許多缺點..
學生還是需要拿一台照相機照螢幕上的內容，不然就是手要不停的寫字，將投影的內容抄到筆記本..
如果是文字內容那還OK,但如果投影的內容是一個圖片一個物體…
哇..學生上完課之後，可能就成為素描專家!!
現在學生人人一支智慧手機 (IPAD/ IPHONE)行動裝置或是筆記電腦 NB,
如果可以透過無線的WIFI 直接將影像傳IPAD/ IPHONE ,
只要輕輕的拿起右手就可以將影像儲存….這樣的互動效果會更好!

我發明了一款白色無線路由器,可以將IPEVO P2V USB 攝影機分享至IPAD/IPHONE…
目前還在實驗階段,如有興趣的朋友可以跟我聯繫

WIFI USB Router+ UVC A/V USB grabber card 等於 WIFI Video Server??

雖然目前IP camera 或 Video server 都已經進化至 H.264壓縮等級
但仍然在市場上面可以看到MJPEG 的Video server..

大部分看到的MJPEG 的Video server 大部分都是帶有 WIFI 的功能,
這類產品的主要行銷對象大多是"居間監看" 的族群..



大家一定很狐疑,現在多媒體H.264 soc 壓縮晶片便宜到在路上都檢的到,

就算是用在居家監看的應用,為何不能用H.264 壓縮呢?
